Broadleaf Weed Control and PRE Crabgrass Control – VIDEO

(By Jared Hoyle and Jake Reeves, KSU Turfgrass Research and Extension)

Just a couple weeks ago the turfgrass team held the Annual Kansas Turfgrass Field day in Manhattan, KS at the Rocky Ford Turfgrass Research Center.  At one of the stops Dr. Jared Hoyle talked about new products that are on the marked for post-emergent broadleaf weed control and pre-emergent crabgrass control.  If you couldn’t make it out to field day here is a short little video about what you missed.

Converting Tall Fescue to Buffalograss – VIDEO

(By Jake Reeves and Jared Hoyle, KSU Turfgrass Research and Extension)

Are you thinking about converting your tall fescue lawn into buffalograss?  If you are, new research is currently being conducted at Rocky Ford Turfgrass Research Center in Manhattan, KS to pin down the best herbicide application timing to reduce the amount of time that you don’t have turf in your lawn.

Check out the video here of KSU Turfgrass Research Technician, Jake Reeves, discuss this research and how it will impact turfgrass areas across Kansas.

“Reflecting on Turfgrass” : KSU NDVI research featured in Golf Course Management

Research by Dr. Dale Bremer and Dr. Steve Keeley along with former students Hyeonju Lee and Kemin Su is featured in Golf Course Management. Check out the article here:

It’s an online e-magazine format and takes a minute to load.

The researchers were studying how NDVI ratings correlate to visual ratings of turfgrass quality. It’s not as simple as you might think! The article at the link above does a nice job summarizing their academic article.

KSU & KDOT Collaborate on Roadside Research Project

Kansas State University, Assistant Professor Jared Hoyle, PhD, along with researchers Jacob Reeves and Evan Alderman, are studying turfgrass on a plot of land on  U.S. 283 near WaKeeney. The two-year-study is testing the right blend of turfgrass that will do well on Kansas roadsides. Please watch the video and let Hoyle explain what they are doing on the side of the road, and how it will be beneficial to all roadsides in Kansas.

The 2016 Turfgrass Research Reports Now Online!

(By Jared Hoyle: KSU Turfgrass Research and Extension)

Every year we create new turfgrass research reports.  This year we have lots of new information from the release of a new zoysiagrass to unmanned aircraft systems for drought monitoring.

Traffic and compaction

(Megan Kennelly, KSU Plant Pathology)

When droughty, wilting turf  is subject to traffic from vehicles, mowers, or even feet, it can develop tracks. If possible, when turf is wilty, avoid traffic altogether. If you must apply traffic, try to do it during cooler parts of the day. Sites with underlying problems like compaction are more prone to drought and therefore more sensitive to traffic.

The KSU Turf Team has several projects related to drought, management, and traffic. Want to learn more? Come out to the Turf Field Day! In addition, stay tuned to this blog for future research updates with specific results from our trials.

tracks

We continue to see samples coming into the diagnostic lab with poor root health, but no pathogens. We got a ton of rain in May, and those root systems declined from too much water. Now that we are into the summer heat, the plants can’t thrive on those compromised root systems. Take note of problem areas, and over time you can try to alleviate compaction, change traffic flows, reduce drainage issues, etc. As much as possible, make the site function at its best to support the plants. You don’t want the site to make things more challenging than it needs to be.

Scholarship and Research Tournament – Thank You!

(Megan Kennelly, KSU Plant Pathology)

I’d like to give a huge thank you to everyone who participated in the Kansas Golf Course Superintendents Association Scholarship and Research Tournament.

The event was held on June 14 at Firekeeper Golf Course. Thanks to Superintendent Rob Christie, Assistant Superintendent Dan Rhule, and the crew for all their hard work getting the site ready. Thanks to Randy Towner, the General Manager and Golf Pro. Thanks to everyone else on staff for making us feel welcome.

In addition, thank you so much for the event sponsors. Here is a list from the KGCSA website showing all the sponsors for the day:

THANKS

Finally, thanks to everyone who came and participated. The funds are used to support KSU scholarships and research. The KSU Turf Team really appreciates your support!
